Abstract

The invention provides an on-line monitor of tail gases of a motor vehicle, relating to the technical field of environmental monitoring instruments. The on-line monitor of the tail gases of the motor vehicle comprises a mainframe, a sampling system, a motor vehicle uphill and downhill judging device, a motor rotating speed measuring system, an oil temperature sensor, a tail gas temperature sensor, a control terminal, an alarm device and a wireless data transmission system, wherein the mainframe comprises a tail gas measuring system and an interface control part and is arranged on a relative clean position inside the motor vehicle, and the tail gases of the motor vehicle enter the tail gas measuring system through the sampling system; the motor vehicle uphill and downhill judging device, the motor rotating speed measuring system, the oil temperature sensor, the tail gas temperature sensor, the alarm device, the wireless data transmission system and the control terminal are respectivelyconnected with the mainframe; and the wireless data transmission system is used for directly transmitting test data to an environmental monitoring master station. The invention can carry out the real-time on-line monitoring on the smoke intensity condition of a diesel motor or the tail gas emission condition of an automobile motor and be widely used for the real-time monitoring of the tail gas emission of the motor vehicle.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring instruments, in particular to monitoring equipment for motor vehicle exhaust. Background technique [0002] As one of the most important means of transportation in modern society, automobiles have brought great convenience to people's life and work, but the exhaust emitted by automobiles has also become another source of air pollution besides soot-type air pollution. Correspondingly, the total amount of vehicle pollutant emissions is rising rapidly. Major cities across the country are seriously polluted by vehicle exhaust. It is of great significance to protect the human living environment by detecting the automobile exhaust pollution. [0003] With the increase of motor vehicles and the improvement of people's environmental awareness, my country has formulated a series of national standards such as GB 18285-2005, GB3847-2005, GB3842-83, GB7258-87, and GB1495-79 on exhaust emiss...
